Virtualized Service Directory (VSD): is the policy engine for the overall platform; network engineers use VSD to make templates that define network functionality for a specific set of resources and users.

Virtualized Service Controller (VSC): uses OpenFlow and OVSDB management protocol to distribute important switching and routing information to hypervisors within the virtual data center network.

Virtual Routing and Switching (VRS): acts as Nuage’s own version of the Open vSwitch, and installs into the hypervisor for software networking.

Nuage Networks VSC Features

Nuage Networks VSC works alongside both the VSD and VRS to make up Nuage’s VSP SDN strategy. Categorized through the VSD, the VSC offers a full view of per-tenant network and service topologies, and represents network service templates. VSC communicates with the VRS software, and is able to drive network virtualization efforts between Layers 2 through 4. VSC also uses standard protocols to peer with existing networks.

Working as the network control plane for data centers, Nuage Networks VSC has a full view of per-tenant network and service topologies. With the VSC, virtual routing and switching constructs are created to program the networking forwarding plane with OpenFlow. Several VSC instances can be organized across data centers by using MP-BGP.
